Heating and Cooling for Kalispell Homes
Your HVAC team on Highway 40, just 18 minutes from Kalispell. Furnace repair, air conditioning, heat pumps, and custom ductwork for the Flathead Valley.
Kalispell is the largest community in the Flathead Valley, and when October rolls around, nearly 30,000 residents start counting on their heating systems to hold through April.
When something goes wrong with your furnace or AC, you want a team close enough to get there fast. The Western Sky shop on Highway 40 in Columbia Falls is 14 miles from Kalispell. That's about 18 minutes by road. In winter, when conditions on US-2 slow things down, our crew builds extra time into the schedule so we're not late when the roads are bad.
Kalispell HVAC Service
Our Columbia Falls crew serves Kalispell, Whitefish, and Columbia Falls with the same flat-rate pricing on every visit. Furnace repair, air conditioning, heat pump installation, custom ductwork, indoor air quality, hydronic heating, and maintenance plans. Licensed and insured. Call 406-296-3336 or use the form on this page.
Natural gas is the primary heating source for most Kalispell homes, with propane in outlying areas and electric resistance heat in some older mobile homes. Wood stoves still supplement in rural properties around the edges of town. Whatever your setup, our team can service it or recommend an upgrade that makes sense for your home and budget.
Your Neighborhood, Your System
Kalispell's housing stock covers a wide range. Older homes near Downtown and Woodland Park have different HVAC needs than newer subdivisions south of town along US-93. Post-war ranch-style homes in Northridge may be running original ductwork that's overdue for evaluation. Newer builds in South Kalispell and West Evergreen often came with high-efficiency systems that still need proper maintenance.
The difference matters when you're choosing a repair, a replacement, or a maintenance plan. Our team evaluates your home, not just your equipment. Kalispell Regional Medical Center, Glacier Park International Airport, the Flathead County Fairgrounds: this is a town that runs year-round. Your comfort system should, too.
What you can count on
Frequently asked questions
Straight answers for Flathead homeowners — phones, service area, and what we do (and don’t) advertise.
What phone number should I save for Western Sky in Columbia Falls / the Flathead?
406-296-3336 — that’s our published Columbia Falls / Flathead residential number. Call that number or use the form on this site.
Do you really come to Kalispell?
Yes. We’re based at our Columbia Falls shop on Highway 40 and schedule the corridor — Columbia Falls, Whitefish, and Kalispell — as capacity allows. Hungry Horse may be available as an optional nested corridor stop; confirm your address when you call 406-296-3336 or send the form.
Is there a different number for Bozeman?
Yes. Bozeman and the Gallatin Valley publish their own number on Bozeman pages. Don’t use the Columbia Falls number as the Bozeman NAP, or vice versa. This page is Flathead residential service — save 406-296-3336.
What about the old Denning number 892-0111?
Legacy 406-892-0111 may still forward into our Columbia Falls line, but it is not a number to save or publish. Save 406-296-3336.
Are you the old Denning Sheet Metal?
Same Columbia Falls shop on Highway 40 (3580 MT-40), new ownership as Western Sky Heating & Cooling (formerly Denning Sheet Metal). A lot of Flathead folks already know the Denning name — and that recent years of service needed a reset. That’s what we’re here for. Call 406-296-3336 or use the form.
Did you merge Denning’s Google reviews into Western Sky?
No. We keep the verified Western Sky listing and mark Denning permanently closed — not merged. Heritage carries through honest naming and citations, not by importing old ratings.
What’s the shop address and website?
3580 MT Hwy 40 W / 3580 MT-40, Columbia Falls, MT 59912 · westernskyhvac.com · Call 406-296-3336.
What heating and cooling work do you do from this hub?
Residential service and replacement from Columbia Falls: furnaces, air conditioning, cold-climate heat pumps, boiler and hydronic heat, indoor air quality, and ductwork built in our own shop. We’re a Lennox dealer for Columbia Falls residential. Call 406-296-3336 or use the form to schedule.
Do you offer maintenance memberships?
Yes — seasonal tune-ups and member preferences as defined on the plan page. Exact monthly pricing publishes when our price book is locked; until then, call 406-296-3336 or use the form and we’ll explain today’s options honestly.
Does Western Sky do plumbing or install water heaters?
Yes. We install and service water heaters. General plumbing is a different conversation — if you’re not sure whether a job is water-heater work we do or something that needs a licensed plumber, call 406-296-3336 and we’ll tell you straight.
Why aren’t the Whitefish and Kalispell URLs at the root?
Our site nests corridor towns under the Columbia Falls engine — for example /columbia-falls/whitefish/... and /columbia-falls/kalispell/.... That’s intentional architecture, not a mistake.
How do I book service?
Call 406-296-3336 or use the form on this page. We’ll get you on the schedule and explain next steps.
